Made-to-measure door systems from South Tyrol
ATP Business GmbH markets its door systems under the ALPGATE brand and manufactures custom-made industrial doors for industry and architecture in South Tyrol. The portfolio includes folding doors, sliding-folding doors, sliding doors, facade doors, revolving corner doors, hangar doors, partition systems and special made-to-measure doors, complemented by fire department doors according to DIN 14092 as well as burglar-resistance doors in resistance classes WK2/RC2 to WK4/RC4 and bullet-resistant versions. Every door is manufactured to measure at the St. Lorenzen/Montal production plant near Bruneck; the constructions are made of steel, galvanized profile sections, stainless steel V2A, aluminium, corten steel, wood, ESG/VSG safety insulating glass and sandwich sheet panels. The value chain ranges from laser cutting of self-supporting substructures to hot-dip galvanizing and powder coating in RAL colors to in-house machine building for door drives, with delivery and installation including substructures offered. With more than 30 years of experience in industrial door construction, ALPGATE supplies customers in Germany, Austria, South Tyrol, Switzerland, Luxembourg and the United Kingdom; references range from AIRBUS Ottobrunn to fire stations, substations and clinics to logistics centers and shopping centers. Sales and service locations are located in Ulm (Germany) and Ebreichsdorf/Vienna (Austria).

Materials and processes
Steel
Highly stable steel structures enable door heights up to 10 m and the use of heavy infill panels.
Stainless steel V2A
Used for corrosion-critical components such as pins, bearings and screws as well as thermally separated glass frames.
Aluminium
Used for perforated sheet infills, ventilation louvers and lightweight partition systems.
Corten steel
Aesthetic material for weather-resistant folding doors without additional coating.
ESG/VSG safety insulating glass
Glazing up to 5 m in height without horizontal mullions, including solar control glazing and stepped glass.
Sandwich sheet panels
42 to 46 mm thick infill panels for insulated doors with high stability.
Hot-dip galvanizing and powder coating
Corrosion protection for doors in aggressive environments, combined with RAL coating.
Laser cutting
Manufacture of self-supporting, laser-cut metal substructures.
Larch/spruce (wood)
Natural material for cladding and door infills in architecture and agriculture.
Thermally separated steel profiles
Special glazing with thermal separation achieves U-values of 1.5–1.6 W/m²K.
Bronze bushings
Hinge components for low-maintenance, long-lasting door movement.
